This is Skógafoss - an enormous waterfall on the south coast of Iceland. The waterfall is about 25m wide with a drop of about 60m (200ft).
As I walked closer to the waterfall the volume of spray intensified and the rainbow you can see in the photo eventually formed a complete circle with my own shadow in the middle. You should just be able to see my shadow against the black volcanic colour of the ground.
There's another photo of this amazing waterfall here which will give you a better idea of it's true size: http://ianbramham.aminus3.com/image/2012-11-06.html
